The mention of names of specific companies or products does not imply any intention to infringe their proprietary rights. chemistry. m. Electrical resistivity and its converse, electrical conductivity, is a fundamental property of a material that quantifies how strongly it resists or conducts the flow of electric current. loses 2 electrons. In the case of Calcium the valence electrons is 2. Or you can write it in noble gas notation and it becomes [He] 2s^2 2p^5. A low resistivity indicates a material that readily allows the flow of electric current. Add your answer and earn points. the electronic configuration of calcium is 2,8,8,2 and so has number of electrons of 20. As a result, neutral helium will only have 2 electrons surrounding its nucleus. It is part of some semiconductors and used in various alloys.
